206 Catalogue of the Birds of Illinois. 



18. C. ossifragu?!, Wils. — S. and E. A species supposed to be peculiar 

 to the vicinity of the sea-coast, but possibly ascendinof the Mississippi and its 

 larger affluents as far as Southern Illinois (see note on page 183). 



Genus Perisoreus, Bonaparte. 



19. P. co««f7e«s/s (Linn.) Bp. Canada .Jay. — N. Obtained by Dr. Hoy, near 

 Racine, Wisconsin, in the winter of 1859 (Nelson, p. 113). Possibly a very rare 

 winter visitant to the extreme northern portion of the state. 



Genus Aphelocoma, Cabanis. 



20. A.floridana (Bartr.) Caban. Florida Jay. — S. E. The Florida .Jay is 

 considered to be peculiar to a limited portion of the peninsula of Florida; but we 

 see no reason to suppose that its range is thus resti'icted. The laws of geo- 

 graphical distribution most emphatically suggest a wider distribution. Indeed, 

 it has been recorded from Kentucky by certain authors; and, though the evi- 

 dence upon which this record was based appears insufficient, it seems extremely 

 probable that, like Peuccea cestwalis, it may eventually be discovered far beyond 

 its previously known range. It is a species which inhabits thickets of bushes 

 or low trees, and should be carefully looked for in such localities, which, in the 

 form of "oak barrens " and the scrubby growth of crab-apple, wild plum, &c., 

 abound in the southern part of Illinois. 



TYRANNID^.— Tyrant Flycatchers. 

 Genus Tyrannus, Cuvier. 



21. T. voctferans, Swains. Gassin's Kingbird. — S. W. A bird of the 

 Great Plains, ranging as far north as Cheyenne, Wyoming. May occur 

 in the semi-prairie districts of Western Illinois. 



22. T. vertical-is, Say. Western Kingbird. — W. A great wanderer, hav- 

 ing been obtained at many eastern localities, as Iowa (Allen, Mem. Boston 

 Soc, L, 1868, 498); New Jersey (Turnbull, Birds E. Penn. & N. J., 1869, 41); 

 Maine (Bryant, Pr. Boston Soc, 1865, 96); and District of Columbia (Jouy, 

 Field and Forest, April, 1877, p. 178). 



Genus Milvulus, Swainson. 



23. M.ti/r annus {liimi.)'Bi>. Fork-tailed Flycatcher. — S. A tropical species, 

 but a great wanderer, having been obtained in several of the eastern United 

 States; e. g. Henderson, Kentucky, New Jersey, and Mississippi (Audubon). 



24. M. forji cat Hs {Gmel.) Sw. Scissor-tailed Flycatcher. — S. W. Essen- 

 tially a southern species (but chiefly Mexican), and, like the preceding, a great 

 wanderer. Common in the semi-prairie districts from Texas to the Indian 

 territory, where known as the " Scissor- tail," and " Bird of Paradise." Has 

 occurred at Fort Riley, Kansas (Snow, Catal. Birds Kansas, 1873, 3), and at 

 Trenton, New Jersey (Abbott, Am. Nat. 1872, 367). 



CAPRIMULGID^.— Goatsuckers. 



Genus Phal/enoptilus, Ridgway. 

 2-5. P. nuttalli (Aud.) Ridgw. Poor-will. — W. Breeds as far east as 

 Eastern Kansas (Allen, Bull. Mus. Comp. Zool., II., 1872, 179; Snow, Catal. 

 Birds Kansas, 1872-3, 3). If occurring in- Illinois, would be found on the dryer 

 prairies.
